1/* AstroReport first-touch attribution (2026-09-07). Same contract as the
2   webapp's src/lib/attribution.ts: records utm_* / src / ref / click ids /
3   referrer / landing path ONCE (first touch wins, 90 days) in localStorage and
4   in the same-domain cookie `ar_attr`, so a click from an email or an ad that
5   lands here still reaches the webapp at astroreport.ai/users/... intact. */
